Abstract—Marine mammals show a unique sound the of the recently revised Moore’s model [4], which is sui-table
species concerned personal identity and certain for steady sound, are in good agreement with that of recent
behavior, automatic identification. Marine mammals measurement data of equal-loudness contours. The
e interesting and important seeking freedom calculation of loudness for temporally variable sounds was
acoustic surveys, wide range animals in their natural given by Zwicker [5] who thought that the specific loudness
habitat. This paper studies the voice of mammals. At in each of certain time segment is dependent upon its
that time, the traditional model of the stability of the frequency spectrum and input level and has a linear relation
hearing voices cannot be used emphasis is placed on with the basilar membrane’s vibration response. In 1999, the
model has been further revised [6]. However, there still have
auditory perceptual model of transient sounds. The main
some drawbacks: (1) the curve of specific loudness versus
idea is the method using STFT position
time has some unreasonable; (2) Temporal masking effect
